ABSTRACT
In our simulations, we carried out the encryption of the Cameraman image with the previously discussed encryption algorithms. Then, the encrypted images were transformed into a binary format and used for orthogonal frequency division multiplexing (OFDM) modulation. Both additive white Gaussian noise (AWGN) and Rayleigh fading channels were considered in the simulations. A normalized carrier frequency offset (CFO) of 0.1 was used in some of the simulation experiments. PAPR reduction techniques were used in some other experiments. In all experiments, 128 subcarriers and quaternary phase shift keying (QPSK) were used. The simulation parameters are summarized in Table 9.1.
